FRN-R-500 - 500Amp Fuse

FRN-R-500 - 500Amp Fuse

With a 500-amp rating and a 10.38-inch blade-ended body, the FRN-R-500 is a fuse you'll want to match carefully to the equipment it's going into. Eaton also specifies a response of 10 seconds at 500% of rated current. In other words, the FRN-R-500 has a very identifiable combination of electrical ratings, blade configuration, and physical dimensions—helpful when you're comparing an existing fuse with the requirements in your equipment documentation.

Key Features and Benefits

• 500A Class RK5 fuse with dual-element construction and a non-indicating design.
• Rated for 250V AC and 125V DC, covering the manufacturer-specified AC and DC voltage ratings for this catalog number.
• Response: 10 seconds at 500% of rated current, as specified by the manufacturer.
• Blade-end × blade-end construction gives the FRN-R-500 its required connection format.
• At 10.38 inches by 2.38 inches by 2.38 inches, the dimensions are particularly important when confirming holder fit and available space.

Material Compliance and Certifications

The manufacturer information supplied for the FRN-R-500 lists the fuse as CE-marked. No additional catalog-specific compliance or certification information was included in the provided specifications, so any required approvals should be confirmed separately for a particular installation.

Where It Works Best

• Equipment requiring an FRN-R-500 or the same complete combination of electrical and physical specifications.
• 500A Class RK5 fuse locations that accept blade-ended connections and the 10.38 × 2.38 × 2.38-inch dimensions.
• 250V AC circuits where a 200 kAIC at 250V AC interrupting rating meets the circuit requirements.
• Installations specifying a dual-element, non-indicating fuse with the stated 10-second-at-500% response characteristic.
